To analyze the characteristrics of polysomnography(PSG) of patients with primary snore and obstructive sleep apneahypopnea syndrome(OSAHS). Method: One hundred and eightythree adults with sleep breathing disorder were studied by 32 guide PSG and analyzed by Polysmith, then they were classified according to the apneahypopnea index(AHI) into four groups: primary snore group, mild OSAHS, moderate OSAHS and severity OSAHS. Result: There were obviously different in NREM stage 1, NREM stage 3, REM, longest apnea, lowest oxygen saturation level(LSaO2), and total arousal index among the four groups. Conclusion: The degree interrelates partly with the structure of sleep, and totally with SaO2 and total arousal index.

To probe into the normal imaging anatomy of the sphenoid sinus and optic canal and its clinical significance. Methods： The sphenoid sinuses and optic canals of 40 normal subjects were examined by MS CT through threedimensional reconstruction method. Results：The length of medial wall, lateral wall ,roof and floor of the optic canal was 12.08±0.62?mm, 10.16±1.73?mm, 9.16±1.17?mm,　and 10.24±1.35?mm, respectively. The width and the height of the intracranial opening ,middle portion, and the intraorbital opening of the optic canal was 5.57±0.95 mm and 4.53±0.78mm，4.40±0.67?mm and 4.36±0.67?mm，　5.09±0.85?mm and 5.90±0.98?mm,　respectively. The distance between the anterior edge of the nasal columella and the middle portion of sphenoid sinus was 7.08±0.54?cm. The maximum transversal diameter of the sphenoid sinus was 17.83±4.38?mm, the maximum vertical diameter was 18.40±3.76?mm, the maximum sagittal diameter was 23.19±6.73?mm. Conclusions： The imaging anatomy of optic canal and sphenoid sinus could be accurately and easily measured by means of threedimentional reconstruction of MS CT, which is of great value to the nasal endoscopic operation of this area.

To estimate the value of salpingocatheterism to treat secretory otitis media (SOM) in patients with nasopharyngeal carcinoma (NPC) after radiotherapy. Methods:The curative effects were analyzed in 106 SOM patients (112 ears) with NPC after radiotherapy by using salpingocatheterism under nasal endoscopic visualization and tympanal retention catheter and intratympanic application of medicine through the eustachian tube. Results: All patients had hearing impairment , tinnitus and blocked feeling, and acoustic immittance test showed that 112 (100%) ears had “Type B” tympanogram. For tinnitus treatment , complete response was found in 81 ears (72.32%), partial response in 25 (22.32%), and no response in 6(5.36%). For blocked feeling, the result was 92(82.14%),18(16.07%), and 2(1.79%) respectively. The total response rate for the above two symptoms was 94.64% and 98.21% respectively. There was no otorrhea. The acoustic immittance test showed “Type A”, “Type As”, “Type B” and “Type C" tympanogran were in 56 ears(50%), 42 (37.50%), 2 (1.79%) and 12 (10.71%), respectively. The mean of 0.5kHz,1?kHz, 2?kHz of puretone hearing thresholds was (28.5±3.0)dBHL, but before treatment it was (47.0±5.0)dBHL. Conclusion: The salpingocatheterism is very effective and practicable to treat SOM in patients with NPC after radiotherapy by supporting and enlarging the eustachian tube.

To discuss the relationship between the stenosed spaces of ostiomeatal complex(OMC), middle nasal conchanasal septum and chronic sinusitis, and the relative factors causing the syenosed spaces. Methods: Eightynine patients(1462 years old,171 sides of nasal cavity and sinus)were examined with coronal and high resolution CT scaning. The CT manifestations of the stenosed spaces of OMC,middle nasal conchanasal septum and the anatomic variations of OMC were comparatively analyzed between the inflammatory sinuses and the normal ones. Result: The stenosed spaces were different between the inflammatory sinuses and the normal ones and there was significant statistically(P<0.01); the OMCs was significantly related with chronic sinusitis(P<0.01). Conclusion: Stenosed spaces of OMC is an important factor causing sinusitis and must be corrected in endoscopic sinus surgery(ESS).

To improve the curative effect of patients with obstructive sleep apnea hypopnea syndrome (OSAHS), we designed and created a new surgery method to enlarge the size of nasopharynx. Methods: Seven male patients with moderate OSAHS since January 2006 were involved in this study. Hard palate was shortened by resecting a portion of posterior hard palate and both hard and soft palate were advanced anteriorly with the surgery of uvulopalatoplasty. Results: All patients retrieved good sleep and energy and the snore disappeared after operation. Conclusion: The results of the study suggested that palatal advancement nasopharyngeal enlargement pharyngoplasty is a more effective treatment with a lower complication rate than standard surgical therapy (uvulopalatopharyngoplasty) for patients with obstructive sleep apnea syndrome.

To study the value of brainstem auditory evoked potential (BAEP) in evaluating the function of brainstem in patients with severe traumatic brain injury in persistent vegetative state(PVS). Methods: Twentyfive patients with severe traumatic brain injury in PVS were examined by BAEP and the data were compared with normal. Results: The abnormal rate of BAEP was 80%(20/25). The alterations included delay of peak latency of I, Ⅲ, and V waves, prolongation of interpeak latency between wave I and V， increase of interaural latency difference of wave V and greater interpeak latency between ⅢV and IⅢ. Conclusion: BAEP can be used to evaluate the function of brainstem in patients with severe traumatic brain injury in PVS and provide evidences for prognosis.

To investigate the value of detecting p21，p73 and PTEN in diagnosis of multiple primary cancers of head and neck. Methods: The expression of p21, p73 and PTEN was detected by SP immunohistochemical stains in 12 patients with multiple primary cancers of head and neck, and the expressive status of p21, p73 and PTEN was compared between the index and second cancer within each patient of these 12 consecutive ones. Results: Between the index and second cancer tissues, the expression of p21, p73 or PTEN protein was different in 7, 3 and 8 cases respectively. The comparison of integrated expression of p21 and p73, p21 and PTEN, p73 and PTEN was not consistent in 8, 9 and 9 cases respectively. The comparison of combined expression of p21, p73 and PTEN was discordant in 10 cases. Conclusion: It can increase the diagnostic sensitivity of multiple primary cancers of head and neck by detecting the combined expression of p21， p73 and PTEN.

To study the characteristics and curative effect of excimer laser in situ keratomileusis (LASIK) for myopia in aged patients. Methods：Fortyeight patients over 40 years (96 eyes) were treated with LASIK, and the preoperative refraction, the refractive diopter supposed to be corrected and the curative effects were compared with the control group (54 patients less 40 years, 108 eyes operated in the same term). Results： The postoperative uncorrected far visual acuity of older myopic patients was 0.97±0.30, which was lower than that of full correction in younger patients operated in the same term (1.18±0.19), but was better than the far visual acuity of supposed refractive diopter in spectacle (0.74±0.16). Near vision of older myopic patients reaching the scale of J1 was lower than contrastive younger group, and complaint of dry eye was obvious more than younger group. Conclusions： LASIK is safe and effective for older myopic patients. Actual corrective diopter may be reduced because of agerelated presbyopia, and the far vision and near vision would be satisfactory postoperatively.

To investigate the effect of IRIS532 overtone laser photocoagulation treatment for diabetic macular edema. Methods: A retrospective study on 45 patients (76 eyes) were analyzed. Of them, 44 eyes of localized edema were treated with direct photocoagulation and 32 eyes of diffuse edema were treated with grid photocoagulation. Vision and fundus fluorescein angiography were analyzed. Results： Among patients with localized edema, visual acuity was improved in 2 lines or more in 10 eyes (22.72%), not changed in 25 eyes(56.82%), and declined in 9 eyes(20.45%), and among patients with diffuse edema, these were respectively in 10 eyes (31.25%), 19 eyes(59.38%) and 3 eyes(9.38%). Among patients with localized edema, edema disappeared in 12 eyes(27.27%), alleviated in 23 eyes (52.27%) and did not changed in 9 eyes(20.45%), and among patients with diffuse edema, these were respectively in 6 eyes(18.75%), 14 eyes(43.75%) and 12 eyes (38.71%). Conclusion： IRIS overtone 532nm laser photocoagulation is more effective for localized edema than for diffuse edema.
